NK0630 : Axial Planar Cleavage

taken 7 years ago, 3 km from Collieston, Aberdeenshire, Great Britain

Axial Planar Cleavage
Axial Planar Cleavage
When rocks are folded, the stress is highest in the tightest part of the fold, called the hinge. The mineral crystals rearrange themselves in the direction of least strain, tending to separate into layers of different minerals parallel to the axial plane. This feature is prominent in the central fold in this view. It is less well developed in the stratum outside this. This is because its mineral assemblage contains less of the types of minerals which tend to form a cleavage.
